The Eclipse Lyo project is focused on providing an SDK to
enable adoption of OSLC
specifications. OSLC (Open Services for Lifecycle Collaboration:
http://open-services.net)
is an open community dedicated to reducing barriers for lifecycle tool
integration. The
community authors specifications for exposing lifecycle artifacts through
uniform (REST)
interfaces and relying on Internet and Linked Data standards.

The project is divided into three categories:

SDKs for developing OSLC integrations

Test suite for OSLC assessment

Samples and reference implementations of OSLC integrations

Lyo is not an Eclipse IDE plugin and is not on the platform
release cycle.

The Lyo 1.1 deliverable is

OSLC4J, a Java SDK for development of applications conforming to OSLC specifications. 1.1 includes a new OSLC Query library and a new OSLC consumer library

A set of OAuth 1.0/1.0a provider libraries to assist with developing OAuth-compliant OSLC applications.

OSLC4J is an SDK for Java application development. It
requires
Java 6 or higher. OSLC4J is based on Apache Jena 2.7.1 or higher and
Apache Wink 1.2.1 or
higher

The Lyo OAuth library are an API to assist with development of OAuth 1.0/1.0a compliant OSLC applications. It requires
Java 6 or higher and makes extenisve use of the Net.OAuth Java libraries.

OSLC4J and the OAuth libraries have a limited number of serviceability messages which are enabled
for translation.
The OSLC test suite is not currently enabled for translation.

The 1.1 API is backward compatible with 1.0

The themes for the 1.1 release of Lyo are:

Provide enhancements and maintentance to the SDK for development of Java OSLC applications.

Provide libraries to assist with development of OAuth-compliant OSLC applications.

Provide test suites to assess the quality of OSLC
implementations.

Provide code samples of OSLC implementations for
developers to use as examples.

OSLC4J is a Java SDK for the development of OSLC applications. It is
based on Apache
Jena and Apache Wink. It provides Java annotations which let
developers represent
OSLC resources as Java objects. The OSLC4J JAX-RS providers assist
with serialziation
and de-serialization of Java OSLC resources to and from RDF/XML and
JSON.

OAuth is a popular Internet authentication protocol and is in common use by linked data applications. The OSLC Core specification
recommends OAuth as a compatible authentication protocol. OAuth is commonly thought of as "difficult" to implement. The Lyo OAuth
libraries have a goal of assisting developers in implementing OAuth-compliant OSLC applicatons. Content includes:

A core library for token issuance, authorization and usage

A consumer store library for token persistence

A webapp library for token issuance and authorization

The OSLC test suite provides a way for developers to assess the
quality of their OSLC
implementations. It contains tests for the OSLC Core specification and for the
following domain specifications:

Asset Management V2

Change Management V1 and V2

Quality Management V2

Requirements Management V2

Automation V2

The test suite also provides reports for easy publication of an
implementations
assessment results.

Lyo contains many samples of OSLC implementations which developers
can use as guides
or starting points for their own implementations. The samples cover
many domain specifications
and include:
